Real-world Dapagliflozin Treatment in Patients With Heart Failure in Portugal (EVOLUTION-HF)

Heart failure (HF) is a global, public health issue that affects more than 63 million people worldwide; this burden is expected to increase substantially as the population ages. Despite advancements in treatment, a HF diagnosis still leads to significant morbidity and mortality; there is also an immense impact on patients' health-related quality of life (HRQoL). On May 5, 2020, the US Food and Drug Administration (FDA) announced the approval of dapagliflozin for heart failure with reduced ejection fraction (HFrEF), regardless of whether the patient has diabetes. Subsequently, there have been additional approvals for this indication by regulatory authorities across the globe." Real-world observational data are necessary to describe dapagliflozin use in real-world settings with detailed clinical data on heart failure symptoms, outcomes, and HRQoL.

About this study

Heart failure (HF) is a global, public health issue that affects more than 63 million people worldwide; this burden is expected to increase substantially as the population ages. Despite advancements in treatment, a HF diagnosis still leads to significant morbidity and mortality; there is also an immense impact on patients' health-related quality of life (HRQoL). On May 5, 2020, the US Food and Drug Administration (FDA) announced the approval of dapagliflozin for heart failure with reduced ejection fraction (HFrEF), regardless of whether the patient has diabetes. Subsequently, there have been additional approvals for this indication by regulatory authorities across the globe." Real-world observational data are necessary to describe dapagliflozin use in real-world settings with detailed clinical data on heart failure symptoms, outcomes, and HRQoL. EVOLUTION-HF will help obtaining relevant insights from clinical practice through the analysis of detailed data on heart failure symptoms/severity for patients receiving dapagliflozin in real-world setting.

Study aims are to describe the characteristics of patients newly prescribed dapagliflozin for the treatment of HFrEF, to provide early insights into real-world dapagliflozin treatment patterns, and to describe patients-reported outcomes, medication adherence and work productivity losses in these patients.

This observational, longitudinal cohort study will include patients with a physician diagnosis of HFrEF who are initiated on dapagliflozin in clinical practice. The study will include 2 cohorts of patients: one fully retrospective and one prospective cohort, in which patient-reported outcomes (PROs) including quality of life will be collected

Secondary outcomes

  1. Absolute change from baseline in Kansas City Cardiomyopathy Questionnaire (KCCQ) score

    Time frame: Measured at 3, 6 and 12 months

    The KCCQ is a 23-item questionnaire that quantifies physical limitations, self-efficacy, social interference and quality of life. Summary scores will be examined at each assessment point during follow-up. For each of the assessment periods, descriptive statistics for the observed value, change from baseline and the 95% two-sided confidence interval for the mean change will be presented. The proportions of participants with overall health status classified as poor, fair, good, and excellent will be examined at each assessment point. Additionally, the proportions of participants who experience clinically meaningful changes in overall health status: improvement (≥5 point increase), deterioration (≥5 point decrease), and stable (<5 point increase or decrease) will be examined at each assessment point.

    Only applicable to Prospective cohort.

  2. Absolute change from baseline in Medication Adherence Report Scale (MARS)-5 questionnaire

    Time frame: Measured at 3, 6 and 12 months

    The MARS-5 is five-item self-report adherence scale which assesses both intentional and non-intentional non-adherence. Respondents rate the frequency with which the five different medication-taking behaviours occur, scoring each item on a 1-5-point scale with higher scores indicating higher reported adherence. The MARS-5 has been shown to be reliable and valid across a variety of health conditions, including cardiovascular and pulmonary diseases.

    Only applicable to Prospective cohort.

  3. Absolute change from baseline in Work Productivity and Activity Impairment (WPAI) score

    Time frame: Measured at 3, 6 and 12 months

    The WPAI is a validated instrument to measure impairments in paid and unpaid work and activities. It measures absenteeism (work time missed), presenteeism (impairment at work / reduced on-the-job effectiveness) as well as the impairments in unpaid activity because of health problems during the past seven days. It has been validated to quantify work impairments for numerous diseases such as asthma, psoriasis, irritable bowel syndrome, and Crohn's disease, but has not yet been validated for use in heart failure participants. Scores will be derived from the overall work impairment at each timepoint and then changes of from baseline will be reported.

    Only applicable to Prospective cohort.
